Quality Control

Our production of (E)-5,5'-(Diazene-1,2-Diyl)Diisophthalic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity for demanding applications. Each lot undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and titration for acid value. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical specifications. We support cGMP and ISO 9001 compliant manufacturing environments upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under dry, inert conditions (e.g., nitrogen or argon atmosphere) for long-term storage to prevent degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
